IMPBOVEMEN T IN PIPE-VISBS.

TO ALL WHOM IT MAY CONORN:

ABe it known that I, DAVID SAUNDERS', oi' Brooklyn', in the county ofKings, and State of' New York, have invented certain new andusefulimprovements in Pipe/Visita by which I mean vises `adapted to holdpipes or other round objects of diii'eren't sizes; and I dohereby-'declare that the following is a full and exact descriptionthereof'.

My improved vise will hold pipes oi' diiferent sizes, and will let themin and out readily by a lateral movement instead of an end'movement, andallows the pipe to be held either upright or at any inclinationrequired. The ability to hold pipes at diii'erent angles is important,because inA cutting threads on the ends, or otherwise treating pipes, itis desirabletohold them as nearly upright as may be, and while shortpieces may be held,

under ordinary circumstances, directly upright, longer pieces require tobe inclined to an extent depending on the length, as will beobvious. Theintroduction and removal of the pipes by a lateral movement, allow thepipes to be removed from my vise after a T-piece, an elbow, or otherxture has been attached at each end. llhere have been many pipe-risesbefore known which possessed these qualities singly, but I know of nonewhich possess them altogether. I employ a peculiarly constructedsliding-jaw as one portion of my vise, which is secured upon theoperating screw in a manner which will be readily understood, and whichaiiords increased strength and firmness to this important connection.

I will proceedlto describe what I consider the best means of carrying`out my invention. vThe accompanying drawings form a partei` thisspecification. l

' Figure 1 isa sectiomon the line S S in iig. 2.

Figure 2 is a plan view-of my vise, showing a pipe held within the jaws.

Similar letters of' reference indicate like parts in all the figures.'Iints are employed only to aid in distinguishing parts, and do notindicate material. The material of the whole may be iron and steel.

A A1 is a casting adapted to be firmly secured upon the bench. by screwsintroduced through the holes a. Al is an upright flange, to the frontface of which is applied a corresponding ange, B1, o f the casting,which contains and supports the effective portions of my vise. Thiscasting entire I will designate generally as B. One ot its mostimportant characteristics is the ample opening, H, provided in one side'adjacent to thejaws, which seize and hold the pipe, and which is ofsuiiicient size to allow the largest pipes or other analogous articlesto be introduced and removed freely by a simple lateral movement. Theentire casting B audits connections turn in various positions, asrequired. The parts A1 and B1, which I have here termed anges, arefinished in theform of nearly circular disks, and are bolted together bya screw-bolt, C, which passes through the centre, of each, by which theforce withwhichthe flanges are held together may be graduated at will.When it is desired to change the position of the casting B, the screw Cmay be slackened, and after B is adjusted the screw C may be tightenedagain.v In many eases itwill suiiice to allow the screw C to bemoderatelyv set up all of the time, so that thecasting maybe adjustedbythe force of a strong hand without touching the screw. Two pieces ofhardened Ysteel having V-shaped dentated recesses, are fitted in thecasting B in the position indicated by b1 b2. 'Ihe'spaceV between themis a little greater than the thickness of one of the pieces, and issufficient to.allow the free entrance of a third piece of steel ofsimilar thickness. Dl Dz are respectively the halves of a slide which-istraversed in the ways B2 B2, in the interior of the casting B, by meansof the screw E, which is capped through the part B3, bolted upon thefront of B, as represented. The parts of this compound slide Dl :D2 arefirmly bolted together by the screw-bolts m. This slide carries'a pieceof hardened steel, d, which is adapted to enter the recess or spacebefore described between the similar pieces h1 b2. The generalarrangement of the pieces b1 t2 and dis adapted to take hold of andfirmly hold the pipes or otherround objects of different diameters,holding them with equal firmness, whether they be one-half inch or twoinches in diam'- eter. When the combined slide DVD2 is driven inward toa great extent, a portion of its steel piece d is received between thesteel pieces 61 b2, and when it is drawn back to its fullest extent thesteel piece'ol is entirely clear from the pieces b1 b2, and allows thepipes to be introduced and removedv by a side movement, as `will bereadily understood. It will be observed that the adjusting in theangular position oi' the entirecasting B and its connections, by turningit 'around upon the piece A, as above suggested, does not in any wiseinterfere with the relations ofthe working parts of the vise to eachother. The screw E, provided with any approved means fortnrning it, isfitted with a strong head, or knob, El, at its inner end, uwhich isreceived within a corresponding recess finished in thc interiors of thetwo halves of the compound slide D1' D2. The neck between the' head E"and body, or threaded` portion of the screw El, is of smaller diameter,and receives strong'and nicely-finished internal lips on the parts D1D2. The parts being properly turned and 'bored-to correspond with eachother, and allow a. tight and easyr fitting, the halves are applied uponthe head El before boing bolted together, and thc setting up of thescrews m confines the parts ofthe compound slide together with the samerigidity as if the whole were one piece, while the Iconnection with thescrew is stronger, and will endure more violent strains than ordinaryfittings of this kind.

Having now fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is as follows: I claim theimproved pipe-vise'herein described, turning on the axis C, and havingthe side opening H, to allow the introduction and removal of the work,the several parts being combined and arranged substantially as and forthe purpose herein set forth.
